It's good, if you have the tracker permanently it needs to be on a charger. After 2 years of use, there were 3 weeks of inactivity and the battery died but it was replaced under warranty as normal

Hello to all interested parties, the battery was purchased on 6/12/2022 from a well-known store in Thessaloniki, price 172€, installed on a Kymco AK550 mega scooter, purchased mainly for the 5-year warranty but also for all the features it has and of course for the 500A starts, basically there is no competitor. Well, starting from the incredible packaging, I was literally amazed by the quality, see photos, also the weight compared to the old Yuasa is day and night, there were various bases inside to be placed on the corresponding compatible scooter, I used the first one where it fit perfectly on the scooter, there is an Allen key to screw the bases where they have 3 different holes, the battery construction quality seems excellent, the start is immediate, I have drawn charging power since I have a compatible NOCO charger, after installation I connected it to see if it was charged but in the 25 minutes I left it, it couldn't charge 100%. I move the scooter 2 times a month, as it is the third one, it is always in a closed parking lot, however, 2 times I started it and the start was immediate even though it was not moving, there will be a future review to see if it is really worth it !!!!! Today 22/12/2022 I connected the charger and in an hour and a half it finally charged to 100%. Well after 2+ months, 19/2/2023, I have only good things to say, I left the scooter for 12 days without starting it and it started immediately again, without any hesitation, today I also charged it after about 2.5 months, charging time up to 100% is about 2 minutes, one thing is for sure that even for the scooter I have, super cup 125, I will choose the same brand even if it costs 105€ !!!!! Well today 7/9/2023 I also installed the same battery (YTX 14 BS) on a BMWR1200GS/2009, used 3 bases this time, I also attach some additional photos, price 172€, I have nothing else to add, except that the start is now immediate !!!!!!! Well the battery that was purchased on 7/9/2923 and installed on a 2009 BMW R1200 GS, from a well-known store in Thessaloniki, burned out, went out, failed on 4/11/2023, unacceptable !!!!! The engine moves once a week and is in a closed parking lot, I returned it and I am waiting for information, on the AK where I have exactly the same one I have no problem I have had it for about a year, I have also sent an email to the US to the Mother company, without any response yet but also to the store where it was purchased. The response from the US, If your battery is not recharging, or if your NOCO charger is remaining in Standby when connecting to the battery, this is likely because the battery's BMS (Battery Management System) has shut the battery down to prevent it from depleting any lower to prevent damage to the battery. This most often occurs due to parasitic drains on the battery from the application. For the quickest results, please disconnect the battery from the vehicle and see solutions below. Keep in mind NOCO NLP batteries are designed to be starting batteries, not deep cycle batteries that would support a large load long term. Finally, the battery was completely replaced. Well, second case with my battery on the AK550, it burned out, stopped suddenly after a year, I removed it and it was replaced, the problem is very serious, unimaginable, imagine being left with nothing suddenly, 2 out of 2, unacceptable !!!!!

Replaced the YUASA YTX 20A-BS. As for the starting currents, you can feel the difference in how it turns the starter, power... and at 1/3 the weight of the old one. Excellent build quality from a factory known for its quality products. It will show how it performs in the cold of winter, but the five-year warranty says a lot.

It has gone through cold, inactivity, heatwaves, and it doesn’t seem to care. It always delivers strong current even after two months of inactivity and has never needed charging; the voltage has never dropped on cold winter mornings to the point where I needed to turn on lights to wake it up.
(In case of very low temperatures, it may appear inactive; what is needed is to turn the key to activate some power source, e.g., fog lights or other lights for a few seconds up to 2 minutes, so the battery warms up and shows voltage again.)

After prolonged inactivity, I did 10km over a period of 4 months, and I needed to start it with a starter. After the engine ran for 1 minute, there was no more starting issue; it charged with a 20-minute ride, bringing the voltage to 13.2V, and after another two weeks of inactivity, it remains there as is normal for it.

It works perfectly as on the first day. Like every lithium battery, if not used frequently to charge and simultaneously has drains like the alarm, it goes into a safety mode to maintain a minimal charge percentage and stay alive; if this didn’t happen, the battery would lose all its charge and wouldn’t recharge, "it would die." With exactly the same logic, our mobile batteries operate, always keeping a minimal charge level, and to achieve this, they turn off the device when it approaches that point. When it enters such a state, it needs charging with the appropriate charger for such batteries, and in a short time, it recovers; these batteries charge very quickly due to their small capacity but at the same time cannot support long-term drains without being charged. I wonder why no one explained the above solution to the companion who experienced this (and the company describes it in their response).
In short, if you don’t have anything on the bike that draws power on a steady basis or have leaks, you won’t have any problems, nor will the voltage drop for a very long time; however, if you don’t use your bike somewhat regularly to charge while simultaneously having other drains during prolonged parking (like the alarm I mentioned), then it will enter a dormant state and will need external charging. You should compromise because lithium batteries have small capacity and are not made to provide power on a long-term basis but with small size and weight to deliver high starting amps; otherwise, choose a good conventional battery. If you choose it, make the investment and buy a suitable charger. There are some that, besides lithium, charge almost all types of batteries used in vehicles; they will pay off in many cases. Personally, I have one that costs 30-40 euros bought from Ali, which also revives vehicle batteries even from very low voltage, where in other cases you would simply replace them, and it has saved me from replacement several times.
